WALLACE NELSON MAYHEW, OF PHILADELPHIA, PENNSYLVANIA.

HINGE FOR VAULT-LIGHT AND OTHER DOORS.

Specification of Letters Patent.

.LPatented July 21, 1908.

Application filed April 1, 1905. Serial No. 253,308.

To all whom it may concern:

.Be it known that I, WALLACE NELsoN MAYHEW, a citizen of the United States, and resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hinges for Vault-Light and Other Doors, of which the following is a specification.

The object of the invention is to provide a hinge capable of general use and especially adapted for use in connection with vault and other lights in that it operates to render them tight and at the same time enables them to he as to all parts thereof comparatively flush with the general level.

To these and other ends hereinafter set forth the invention comprises the improvements to be presently described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a transverse sectional view of a hinge, embodying features of my invention,

applied to a vault light construction. Fig. 2, is a top or plan View of the hinge. Fig. 3, is anv end elevational view of the same. Fig.

4, is a view showing the parts of the hinge in different positions from those shown in Fig. 3. Fig. 5, is a central sectional view showing the parts of the hinge detached; and Figs. 6 and 7, are elevational views drawn to a reduced scale showing the respective sides of one member of the hinge.

In the drawings 1, is an angle member having its sides parallel and having a knuckle 2 arranged at the end of and beneath one of its flanges 3. The other flange 4, is adapted to constitute attaching means.

5, is a second angle member having a top flange 6, and having a notch which opens at the top as at 7, and also penetrates the side wall 8, as at 9. Said notch serves to accommodate the knuckle 2, and its flange 8. The member 5, is provided between its flanges with a closed housing 10.

11, is a pintle supported by the end walls of the housing and arranged to penetrate the opening in the knuckle 2 and so constitute the hinge pin. The flanges 3 and 4, are arranged beneath and between the angle bar 12, which constitutes the rim bar of the door and the flange 8 of the member 5 is secured to the upwardly extending flange of the angle bar 13 that constitutes the door frame. It will thus be seen that the door projects above the general level only to the extent of the thickness of the flange 12, which is usually comparatively thin, so that the faces of the doors lie substantially flush with the general construction. The housing 10 serves to catch and retain any water that may leak past the member 1 and thus prevents it from escaping past the construction or leaking into the compartment covered thereby.

It will be obvious to those skilled in the art to which my invention relates that modifications may be made in details without departing from the spirit thereof, hence the invention is not limited further than the prior state of the art may require, but

Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters Patent is 1. In combination an angle member having a knucklearranged subjacent one of its flanges and having its other flange adapted to constitute attaching means, a second angle member notched at its top and side walls for the accommodation of said knuckle and its flange and provided between its flanges With a closed housing communicating with said notch, and a pintle supported by the end walls of the housing and upon which the knuckle works, substantially as described.

2. In combination the outwardly flanged rim bar of a vault light door, the upwardly flanged rim of the door frame, an angle member having a knuckle arranged subj acent one of its flanges and having both its flanges in abutment with the inner faces of the flanges of the rim bar, a second angle member notched at its top and side walls for the accommodation of said knuckle and its flange and provided between its flanges with a closed housing communicating with said notch and the side wall of said second Inember abutting upon the upward flange of the door frame, and a pintle supported by the end Walls of the housing and upon which the knuckle turns, substantially as described.

3. In combination a vault light door and frame for the door and a hinge interposed between the two and consisting of an angle member having a knuckle arranged subjacent one of its flanges, a second angle member notched at its .top and side walls for the accommodation of said knuckle and its flange and provided with a closed housing communicating With said notch, and a pintle supported by the end Walls of the housing, substantially as described.

4. In combination a member having a knuckle on one end, a second member provided with a housing closed at its bottom and ends and open at its top and notched at one of its edges, and said second member adapted to receive the knuckle, and a hinge pin arranged in the housing and cooperating with the knuckle, substantially as described.

5. In a device of the character described, a hinge comprising a plurality of members, one of said members having a top face, a recess therein and an upwardly-projecting inner Wall, and the other of said members being of angular shape and having a thickened portion pivotally mounted in said recess and an angularly deflected portion adapted to be attached to the desired point, the juxtaposed top faces of said hinge members being flush When in normal position.

In testimony whereof I have hereunto signed my name.
